A research objective was reception macro-microscopic and the morphometric data
about glands which are settling down in the field of internal urethral
sphincter, right and left ureteric sphincters at people of different age. Macro-microscopy
and morphometry methods have studied glands sphincters on 54 total preparations
of a urinary bladder received from corpses of people of different age (from
newborn till the senile period), without a pathology of bodies to device urine-genital.
The glands were painted by 0, 05% methylene blue solution and were investigated
with the application of stereomicroscopic-binocular microscope MBS-9. For reception
of micro preparations cuts sphincters zones of a bladder in the thickness 5-7
microns were stained with hematoxylin-eosin, azure-2-eosin, with hematoxylin-picrofucsin
by Van-Gizon technique. Researches included calculation of arithmetic-mean indicators,
their errors. Reliability of distinctions defined a method of confidential
intervals. On total preparations, in area sphincters zones of the human urinary
bladder, the glands as a rule, have in regular interval and often congestions
- «the gland muff» form. The glands in area sphincters zones, as
a rule, settle down densely; without dependence from age, length and width of
initial department of glands of these zones more than in outside sphincters.
Throughout of the postnatal ontogenesis dimensional indicators of glands in
sphincters bladder zones essentially changes. Without dependence from age, under
our data, in a zone internal urethral sphincters length of initial department
1,2-1,6 times, and width of initial department – in 1,2-1,5 times more
than in next (outside) to a zone. Length of initial department of glands in
the field of right and left sphincters, under our data, also in 1,2-1,8
times, and their width – in 1,2-1,3 times more than near these sphincters.
And these indicators at right and left uretheric sphincters almost correspond
each other. The maximum values these indicators reach in 1st period
of mature age in the internal urethral sphincter. At the same time, these indicators
at right and left uretheric sphincter almost correspond each other that, possibly,
are caused by essentially similar design. Length of initial departments of glands
in the internal sphincters a bladder, in comparison with next (out the sphincters)
a zone newborn children have more in 1, 2 times, in the early childhood and
at teenagers - 1,4 times, a corresponding indicator it is equal in 1st
period of mature age - 1,5. The minimum individual indicators of length and
width of initial departments in sphincters zones also more than near to them
that correspond to great values of average indexes. As in sphincters, and outside
sphincters areas, under our data, the maximum values the length and width of
initial departments reaches in 1st period of mature age, when this
indicator authentically more than at newborn children and at senile age.
